The invention discloses a cold heading formation technology of a grid structure bolt. The cold heading formation technology of the grid structure bolt comprises the steps of preparing raw materials, transforming the raw materials, conducting cold heading formation, milling grooves, conducting quenching, conducting tempering, conducting blackening treatment and conducting post-treatment. The cold heading formation technology of the grid structure bolt solves the problems of delayed crack and fatigue crack of the bolt under high strength, the bolt is not prone to breakage in the use process, connection is reliable, the service life of the bolt is prolonged, and the use demand, for the high-strength bolt for a steel grid structure bolt sphere joint, of the current society can be better met.
